CROSS-REFERENCE TO RELATED APPLICATION

Pursuant to 35 U.S.C. § 119(a), this application claims the benefit of earlier filing date and right of priority to Korean Application No. 10-2017-0117384, filed on Sep. 13, 2017, the contents of which are hereby incorporated by reference herein in their entirety.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a driving assistance apparatus for a vehicle, which sets a lane-level recommended path based on a road-level set path and data received from a other vehicle.

2. Description of the Related Art

A vehicle is an apparatus that moves in a direction desired by a user riding therein. A representative example of a vehicle may be an automobile.

Recently, vehicles have been equipped with various types of sensors and electronic devices for convenience of a user. In particular, Advance Driver Assistance Systems (ADASs) are being studied and researched briskly to help a user drive easily and conveniently. In addition, efforts have been being made to study and develop a driving system for a vehicle, which enables the vehicle to travel autonomously.

Vehicle-to-everything (V2X) communication technologies is performed by a vehicle to communicate with another device while on the move. While on the move, the vehicle receives various types of data from another vehicle, a mobile terminal possessed by a pedestrian, an infrastructure facility installed on the road, a server which provides traffic information, etc. The vehicle may determine a surrounding situation using the received data, and may autonomously travel without manipulation of a driver or perform a driver assistance function.

A driving assistance apparatus may determine a location of a vehicle based on GPS location information of the vehicle, and determine a location of a other vehicle based on GPS location information of the other vehicle.

Generally, GPS location information is given with road-level precision. Precision indicates a degree of how detailed a map is presented. For example, if location information of a vehicle is give with road-level precision, the driving assistance apparatus may determine, based on the location information, a road in which the vehicle is located. In this case, however, the driving assistance apparatus is not allowed to determine a lane in which the vehicle is located. On the other hand, if the location information of the vehicle is give with lane-level precision, the driving assistance apparatus may determine, based on the location information, even a lane in which the vehicle is located.

Accordingly, in the case of determining a location of a vehicle using GPS location information, the driving assistance apparatus is able to determine a road-level location of the vehicle, but unable to determine a lane-level location thereof.

In addition, a set path for a vehicle is generally given with road-level precision. Therefore, the driving assistance apparatus is able to display, on a map displayed on a navigation display, a road-level path required for the vehicle to travel, but unable to display a lane-level path therefor.

Recently, technologies for recommending a lane-level path using data transmitted by other vehicles travelling along a set path for a host vehicle have been being researched and developed.

FIG. 9 is a flowchart illustrating operation of a driving assistance apparatus according to an embodiment of the present invention. FIG. 10 is a diagram illustrating how a driving assistance apparatus according to an embodiment of the present invention sets a lane-level recommended path using a road-level set path.

Referring to FIGS. 9 and 10, operation of the driving assistance apparatus 800 will be described.

The processor 850 acquires information about a set path for the vehicle 100 in S100.

The set path for the vehicle 100 include a path previously travelled by the vehicle 100 and a predicted path to be travelled by the vehicle 100.

The set path for the vehicle 100 is a path with road-level precision.

Precision of a path is a degree of how detailed the path is presented on the map. For example, precision of a path may be expressed either as road level or lane level.

FIG. 10 shows a set path with road-level precision, and a recommended path with lane-level precision.

When a set path SP has road-level precision, the set path SP is displayed as a road on the map. In this case, a road to be travelled by the vehicle 100 may be displayed on the map, but a lane to be travelled by the vehicle 100 is not displayed.

Based on information about the set path SP, the processor 850 may determine which road the vehicle 100 needs to travel.

However, when the road includes multiple lanes, the processor 850 is not able to determine which lane the vehicle 100 needs to travel, based on the information about the set path SP.

That is, the processor 850 may determine only a road-level set path SP, based on the information about the set path SP which is presented with road-level precision.

Lane-level precision is greater than road-level precision.

A path with Lane-lever precision is more detailed than a path with road-level precision.

When a recommended path RP is presented with lane-level precision, the processor 850 may determine which lane the vehicle 100 needs to travel, based on information about the recommended path RP.

That is, when the recommended path RP has road-level precision, the processor 850 may determine a lane-level recommended path RP, based on information about the recommended path RP.

At least one of the navigation system 770, the driving system 710, and the controller 170 may generate information about a set path for the vehicle 100. At least one of the navigation system 770, the driving system 710, and the controller 170 may provide the information about a set path for the vehicle 100 to the processor 850.

Through the interface unit 830, information about a set path, the processor 850 may acquire which is provided by at least one of the navigation system 770, the driving system 710, and the controller 170.

Through the communication apparatus 400, the processor 850 may receive V2V data transmitted by one or more other vehicles in S200.

In some embodiments, step S100 and Step S200 may be performed simultaneously or may be in reverse order of the drawing.

While travelling, the vehicle 100 or other vehicle may broadcast V2V data within a preset range of distance. Accordingly, the vehicle 100 may receive V2V data broadcasted by the other vehicle.

V2V data may include information about a vehicle which has transmitted the V2V data, or may be information acquired by the vehicle 100 or the other vehicle while travelling.

For example, the V2V data may be a Basic Safety Message (BSM).

For example, the V2V data may include GPS location information of a vehicle which has transmitted the V2V data, speed information, information about a set path, information about an error state, information about a control state, and information about a driving mode.

For example, the V2V data may include surrounding image information acquired by a vehicle which has transmitted the V2V data, sensing information, traffic information, and surrounding situation information.

Referring to FIG. 10, the vehicle 100 and a plurality of other vehicles 101 to 107 broadcast their respective V2V data. Accordingly, through the communication apparatus 400, the processor 850 may receive, V2V data respectively broadcasted by the plurality of other vehicles 101 to 107.

The processor 850 may select data of interest from one or more V2V data in S300.

Based on information about a set path and one or more V2V data, the processor 850 may select, from the one or more V2V data, data of interest which is V2V data transmitted by a vehicle of interest which is a other vehicle located on the set path.

Based on the information about the set path and the one or more V2V data, the processor 850 may determine whether or not a vehicle of interest located on the set path exists.

When it is determined that the vehicle of interest located on the set path exists, the processor 850 may determine that V2V data transmitted by the vehicle of interest is data of interest. When it is determined that the vehicle of interest located on the set path exists, the processor 850 may filter out V2V data other than the V2V data transmitted by the vehicle of interest.

Referring to FIG. 10, based on V2V data respectively broadcasted by a plurality of other vehicles 101 to 107, the processor 850 may determine respective transmission locations of a plurality of V2V data.

Vehicles of interest located on the set path SP among the plurality of other vehicles 101 to 107 are a first other vehicle 101, a second other vehicle 102, and a third other vehicle 103.

Based on V2V data respectively transmitted by the first other vehicle 101, the second other vehicle 102, and the third other vehicle 103, the processor 850 may determine that the first other vehicle 101, the second other vehicle 102, and the third other vehicle 103 are vehicles of interest located on the set path SP.

The processor 850 may select the V2V data, which are respectively transmitted by the first other vehicle 101, the second other vehicle 102, and the third other vehicle 103, as data of interest.

The processor 850 may filter out V2V data transmitted by the other vehicles 104 to 107 other than the first other vehicle 101, the second other vehicle 102, and the third other vehicle 103.

The processor 850 may set a recommended path for the vehicle 100 based on the data of interest in S400.

The recommended path set by the driving assistance apparatus 800 is a path with lane-level precision. The lane-level precision is greater than road-level precision.

When the recommended path RP has lane-level precision, the processor 850 may determine which lane the vehicle 100 needs to travel, based on information about the recommended path RP.

That is, when the recommended path RP has lane-level precision, the processor 850 may determine a lane-level recommended path RP based on information about the recommended path RP.

A method of setting a recommended path will be described later in more detail with reference to FIG. 11.

Referring to FIG. 10, the processor 850 may determine a recommended path RP based on V2V data respectively transmitted by the first other vehicle 101, the second other vehicle 102, and the third other vehicle 103.

FIG. 11 is a flowchart illustrating a procedure by which the driving assistance apparatus according to an embodiment of the present invention selects data of interest and sets a recommended path.

The processor 850 may acquire information about a set path for the vehicle 100 and V2V data respectively transmitted by one or more other vehicles in S200.

One or more V2V data may include GPS location information of vehicles which have respectively transmitted the one or more V2V data.

In S310, the processor 850 may determine whether data of interest exists in one or more V2V data, based on GPS location information included in each of the one or more V2V data.

Based on information about a set path and the GPS location information included in each of the one or more V2V data, the processor 850 may determine whether data of interest which has been transmitted from a location on the preset path exists in the one or more V2V data.

When such data of interest exists, the processor 850 filters out data other than the data of interest from the one or more V2V data in S320.

The driving assistance apparatus 800 reduces load of received data, by filtering out V2V data other than data of interest when setting a recommended path.

The processor 850 determines a lane-level location of a vehicle of interest and a lane-level location of the vehicle 100 in S410.

The processor 850 may determine the lane-level location of the vehicle of interest based on the data of interest.

The one or more V2V data may include GPS location information of each of the one or more other vehicles which have respectively transmitted the one or more V2V data, and surrounding image information acquired by each of the one or more other vehicles. Accordingly, the data of interest may include GPS location information of a vehicle of interest which has transmitted data of interest, and surrounding image information acquired by the vehicle of interest.

The GPS location information may be given with road-level precision. Accordingly, when determining a location of a vehicle using the GPS location information, the processor 850 is able to determine which road the vehicle is located, but unable to determine which lane the vehicle is located.

That is, when determining a location of a vehicle based on general GPS location information, it is not possible to determine which lane the vehicle is located. Thus, the driving assistance apparatus 800 utilizes GPS location information and surrounding image information in order to determine a road and a lane in which the vehicle is located.

The processor 850 may determine a lane-level location of a vehicle of interest based on GPS location information and surrounding image information of the vehicle of interest included in data of interest.

To this end, the processor 850 may determine a road-level location of the vehicle of interest, based on GPS location information of the vehicle of interest. The processor 850 may determine which lane the vehicle of interest is located, based on the determined road-level location of the vehicle of interest and surrounding image information acquired by the vehicle of interest. Accordingly, the processor 850 may determine a lane-level location of the vehicle of interest.

The surrounding image information may be information about images acquired by one or more cameras provided in the vehicle 100. For example, the surrounding image information may be information about images acquired by at least one of a front camera, a rear camera, and a side camera of the vehicle 100.

The processor 850 may determine a lane-level location of the vehicle 100 based on vehicle state information.

The interface unit 830 may acquire the vehicle state information from various devices provided in the vehicle 100. The vehicle state information may include GPS location information of the vehicle 100, and surrounding image information acquired by the camera 310 provided in the vehicle 100. For example, the interface unit 830 may acquire the surrounding image information of the vehicle 100 from the camera 310. For example, the interface unit 830 may acquire GPS location information of the vehicle 100 from the navigation system 770 or the location information unit 420.

The interface unit 830 may transmit, to the processor 850, vehicle state information which indicates a state of any of various devices included in the vehicle 100.

The processor 850 may acquire, through the interface unit 830, the vehicle state information from any of various devices included in the vehicle 100.

The processor 850 may determine a lane-level location of the vehicle 100 based on GPS location information and surrounding image information of the vehicle 100 included in the vehicle state information.

To this end, the processor 850 may determine a road-level location of the vehicle 100 based on the GPS location information of the vehicle 100. The processor 850 may determine which lane the vehicle 100 is located on the road, based on the road-level location of the vehicle 100 and surrounding image information acquired by the camera 310. Accordingly, the processor 850 may determine the lane-level location of the vehicle 100.

Based on a determined lane-level location determined for a vehicle of interest, a determined lane-level location of the vehicle 100, data of interest, and vehicle state information, the processor 850 may determine a recommended speed or risk level for a lane in which the vehicle of interest is located (hereinafter, referred to as a “lane of interest) in S420.

The data of interest may include at least one of information about the vehicle of interest and information acquired by the vehicle of interest.

For example, data of interest may include GPS location information of a vehicle of interest which transmits data of interest, speed information of the vehicle of interest, information about a set path of the vehicle of interest, information about an error state of the vehicle of interest, information about a control state of the vehicle of interest, and information about a driving mode of the vehicle of interest.

For example, data of interest may include surrounding image information acquired by a vehicle of interest which transmits the data of interest, sensing information acquired by the vehicle of interest, traffic information acquired by the vehicle of interest, and information about a surrounding situation acquired by the vehicle of interest.

The processor 850 may determine at least one of a recommended speed and a risk level for a lane of interest, based on at least one of the following: speed information of a vehicle of interest included in data of interest, information about an error state, information about a control sate, information about a driving mode, sensing information, traffic information, and information about a surrounding situation.

The recommended speed may be a speed at which the vehicle 100 can travel safely in a specific lane without colliding with any other vehicle.

The risk level may correspond to a value which corresponds to a probability for the vehicle 100 to collide with an object in a specific lane.

For example, the risk may be expressed as a numerical number which indicates a dangerous degree of a corresponding lane. For example, the risk may be expressed in a range of numerical values between 0 and 2. In this case, a greater value may indicate a higher risk.

A method of determining a recommended speed or risk level for a lane of interest will be described later in more detail with reference to FIG. 14.

When a road corresponding to a set path is determined to be a multilane road, the processor 850 may determine a recommended speed or risk level for each lane of the multilane road, based on a determined lane-level location of a vehicle of interest, a determined lane-level location of the vehicle 100, data of interest, and vehicle state information.

Based on surrounding situation information, the processor 850 may determine whether the road corresponding to the set path is a multilane road.

The surrounding situation information is information indicating an environment or situation in the surroundings of a vehicle. For example, object information acquired by the object detection apparatus 300 corresponds to the surrounding situation information. For example, out of communication information received by the communication apparatus 400 from the external communication apparatus 400, information about an area in which the vehicle 100 is travelling, traffic condition information, and information about an other vehicle correspond to the surrounding situation information. For example, out of navigation information provided by the navigation system 770, map information, traffic information, law information, and location information of the vehicle 100 correspond to the surrounding situation information.

The interface unit 830 may acquire the surrounding situation information from various devices included in the vehicle 100, and transmit the acquired surrounding situation information to the processor 850.

In S430, the processor 850 may set a recommended path, based on a determined lane-level location of the vehicle 100 and a recommended speed or risk level for a lane of interest.

When the road corresponding to the set path is a multilane road, the processor 850 may set a recommended path, based on the determined lane-level location of the vehicle 100 and a recommended speed or risk level for each lane of the multilane road.

For example, when a driving mode of the vehicle 100 is determined to be a speed mode based on vehicle driving information, the processor 850 may set a path, which has the highest recommended speed among multiple lanes, as a recommended path, based on a recommended speed for each lane of the multilane road.

The vehicle state information may include information about a driving mode of the vehicle 100. For example, the driving mode of the vehicle 100 may include a speed mode in which the vehicle 100 can reach a destination as fast as possible, and a safe mode in which the vehicle 100 can travel as safely as possible.

For example, when the driving mode of the vehicle 100 is determined to be the safe mode based on vehicle driving information, the processor 850 may set a path, which has the lowest risk level among multiple lanes, as a recommended lane, based on respective risk levels for the multiple lanes.

The processor 850 may display the recommended path on the display unit 251.

For example, the processor 850 may display, on the display unit 251, a map image which indicates the recommended path.

For example, the processor 850 may display an arrow or a guideline, which indicates the recommended path, with augmented reality on a transparent display provided in the windshield. In this case, a driver of the vehicle may recognize such that the image indicating the recommended path is displayed on the road.

When a recommended speed for each lane included in a set path is determined, the processor 850 may display the recommended speed on the display unit 251.

The processor 850 may display, on the display unit 251, a lane in which the vehicle 100 is travelling among multiple lanes and a recommended speed for the lane. For example, when the vehicle 100 is in the manual mode, the processor 850 may display, on the display unit 251, a recommended speed for the lane in which the vehicle 100 is travelling.

The processor 850 may control the vehicle drive apparatus 600 so that a speed of the vehicle 100 becomes the recommended speed for the current lane of travel in which the vehicle 100 is travelling among one or more lanes. For example, when the vehicle 100 is in the autonomous mode, the processor 850 may control the vehicle drive apparatus 600 so that the vehicle 100 travels at the recommended speed for the current lane of travel.

When risk levels for one or more lanes included in a set path is determined, the processor 850 may display the respective risk levels on the display unit 251.

The processor 850 may display, on the display unit 251, a risk level for the current lane of travel in which the vehicle 100 is travelling among one or lanes included in the set path.

FIGS. 12 and 13 are diagrams illustrating a road-level location and a lane-level location.

FIG. 12A shows an example in which GPS location information is given with road-level precision.

As GPS location information provided by the first vehicle 101 is given with road-level precision, a location indicated by the GPS location information provided by the first vehicle 101 may be represented as a first region G1. As GPS location information provided by the second vehicle 102 is given with road-level precision, a location indicated by the GPS location information provided by the second vehicle 102 may be represented as a second region G2. As GPS location information provided by the third vehicle 103 is given with road-level precision, a location indicated by the GPS location information provided by the third vehicle 103 may be represented as a third region G3.

FIG. 12B shows locations of other vehicles determined by the processor 850.

The processor 850 may determine a road-level location of each of the first, second, and third vehicles 101, 102, and 103 based on the GPS information provided by each of them.

As the GPS location information provided by the first vehicle 101 is given with road-level precision, the processor 850 may determine that the first vehicle 101 exists in a first region L1, based on the GPS location information provided by the first vehicle 101.

As the GPS location information provided by the second vehicle 102 is given with road-level precision, the processor 850 may determine that the second vehicle 102 exists in a second region L2, based on the GPS location information provided by the second vehicle 102.

As the GPS location information provided by the third vehicle 103 is given with road-level precision, the processor 850 may determine that the third vehicle 103 exists in a third region L3, based on the GPS location information provided by the third vehicle 103.

Accordingly, using GPS location information, the processor 850 is able to determine which road each vehicle is located, but unable to determine which lane each vehicle is located. The driving assistance apparatus 800 according to the present invention may determine which lane an other vehicle is located, based on GPS location information and surrounding image information.

FIG. 13A shows regions G1, G2, and G3 indicating precision of GPS location information, and fields of view C1, C2, and C3 of front cameras of vehicles.

In the drawing, the first vehicle 101, the second vehicle 102, and the third vehicle 103 acquire front images using front cameras. In some embodiments, however, the first vehicle 101, the second vehicle 102, and the third vehicle 103 may acquire image using side or rear cameras in some embodiments.

The first vehicle 101, the second vehicle 102, and the third vehicle 103 may broadcast information about the acquired front images as V2V data.

The processor 850 may acquires front image information broadcasted by each of the first vehicle 101, the second vehicle 102, and the third vehicle 103.

FIG. 13B shows locations of other vehicles determined by the processor 850.

The processor 850 may determine a lane-level location of each of the first vehicle 101, the second vehicle 102, and the third vehicle 103, based on GPS location information and image information provided by each of them.

The processor 850 may determine that the first vehicle 101 exists in the first region G1, based on GPS location information and front image information provided by the first vehicle 101. Accordingly, the processor 850 may determine that the first vehicle 101 is located in a second lane.

The processor 850 may determine that the second vehicle 102 exists in the second region G2, based on GPS location information and front image information provided by the second vehicle 102. Accordingly, the processor 850 may determine that the second vehicle 102 is located in a third lane.

The processor 850 may determine that the third vehicle 103 exists in the third region G3, based on GPS location information and front image information provided by the third vehicle 103. Accordingly, the processor 850 may determine the third vehicle 103 is located in a fourth lane.

FIG. 14 is a diagram illustrating how a driving assistance apparatus according to an embodiment of the present invention determines a recommended speed or risk level for each lane of a multilane road.

In the example of FIG. 14, a first vehicle 101, a second vehicle 102, a third vehicle 103, and a fourth vehicle 104 are located on a road corresponding to a set path and therefore considered to be vehicles of interest. Because the set path includes a previous road travelled by the vehicle 100 and a predicted road to be travelled by the vehicle 100, the third vehicle 103 and the fourth vehicle 104 located behind the vehicle 100 are vehicles of interest.

Vehicle state information may include speed information of the vehicle 100. Data of interest may include speed information of a vehicle of interest.

The processor 850 may determine a speed of the vehicle 100 based on the speed information of the vehicle 100.

In some embodiments, the processor 850 may determine a speed of each of the first vehicle 101, the second vehicle 102, the third vehicle 103, and the fourth vehicle 104 based on speed information provided by each of them.

The processor 850 may determine a risk level for each lane of a multilane road lanes based on a determined lane-level location of a vehicle of interest, a determined lane-level location of the vehicle 100, the speed information of the vehicle 100, and the speed information of the vehicles of interest.

When a vehicle of interest is determined to be located behind the vehicle 100, the processor 850 may determine that a risk level for a lane in which the vehicle of interest is located is proportional to a value obtained by subtracting the speed of the vehicle 100 from a speed of the vehicle of interest.

For example, when a value obtained by subtracting the speed of the vehicle 100 from a speed of a vehicle of interest located behind the vehicle 100 is a positive value greater than a first reference value, the processor 850 may determine that a lane in which the vehicle of interest is located has the highest risk level. For example, the highest risk level may be represented as 2.

For example, when a value obtained by subtracting the speed of the vehicle 100 from a speed of vehicle of interest located behind the vehicle 100 is a positive value which is equal to or smaller than the first reference value and greater than the second reference value, the processor 850 may determine that a lane in which the vehicle of interest is located has a normal risk level. For example, the normal risk level may be represented as 1.

For example, when a value obtained by subtracting the speed of the vehicle 100 from a speed of a vehicle of interest located behind the vehicle 100 is 0 or a negative value, the processor 850 may determine that a lane in which the vehicle of interest is located has the lowest risk level. For example, the lowest risk level may be represented as 0.

The first reference value and the second reference value may be determined through experiments or may be set by a user. Associated data may be stored in the memory 820.

In the example of FIG. 14, the processor 50 may determine that the third vehicle 103 and the fourth vehicle 104 are located behind the vehicle 100, based on surrounding situation information or data of interest.

The processor 850 may perform a calculation of subtracting the speed of the vehicle 100 from a speed of the third vehicle 103. The processor 850 may determine that a risk level for the fourth lane L4 in which the third vehicle 103 is located is proportional to a value obtained by subtracting the speed of the vehicle 100 from the speed of the third vehicle 103. Accordingly, when the vehicle 100 is travelling at a constant speed, the processor 850 may determine such that the faster speed of the third vehicle 103, the higher risk level for the fourth lane L4. In addition, when the third vehicle 103 is travelling at a constant speed, the processor 850 may determine such that the slower speed of the vehicle 100, the higher risk level for the fourth lane L4.

The processor 850 may perform a calculation of subtracting the speed of the vehicle 100 from a speed of the fourth vehicle 104. The processor 850 may determine that a risk level for the first lane L1 in which the fourth vehicle 104 is located is proportional to a value obtained by subtracting the speed of the vehicle 100 from the speed of the fourth vehicle 104. Accordingly, when the vehicle 100 is travelling at a constant speed, the processor 850 may determine such that the faster speed of the fourth vehicle 104 behind the vehicle 100, the higher risk level for the first lane L1. In addition, when the fourth vehicle 104 is travelling at a constant speed, the processor 850 may determine such that the slower speed of the vehicle 100, the higher risk level for the first lane L1.

When a vehicle of interest is determined to be located ahead of the vehicle 100, the processor 850 may determine that a risk level for a lane in which the vehicle of interest is located is proportional to a value obtained by subtracting the speed of the vehicle 100 from a speed of the vehicle of interest.

For example, when a value obtained by subtracting the speed of the vehicle 100 from a speed of a vehicle of interest located ahead of the vehicle 100 is a positive value greater than a first reference value, the processor 850 may determine that a lane in which the vehicle of interest is located has the highest risk level. For example, the highest risk level may be represented as 2.

For example, when a value obtained by subtracting the speed of the vehicle 100 from a speed of a vehicle of interest located ahead of the vehicle 100 is a positive value which is equal to or smaller than the first reference value and greater than a second reference value, the processor 850 may determine that a risk level for a lane in which the vehicle of interest is located has a normal risk level. For example, the normal risk level may be represented as 1.

For example, when a value obtained by subtracting the speed of the vehicle 100 from a speed of a vehicle of interest located ahead of the vehicle 100 is 0 or a negative value, the processor 850 may determine that a lane in which the vehicle of interest is located has the lowest risk level. For example, the lowest risk level may be represented as 0.

The first reference value and the second reference value may be determined through experiments or may be set by a user. Associated data thereof may be stored in the memory 820.

In the example of FIG. 14, the processor 850 may determine that the first vehicle 101 and the second vehicle 102 are located ahead of the vehicle 100, based on surrounding situation information or data of interest.

The processor 850 may perform a calculation of subtracting a speed of the first vehicle 101 by the speed of the vehicle 100. The processor 850 may determine that a risk level for the second lane L2 in which the first vehicle 101 is located is proportional to a value obtained by subtracting the speed of the vehicle 100 from the speed of the first vehicle 101. Accordingly, when the vehicle 100 is travelling at a constant speed, the processor 850 may determine such that the slower speed of the first vehicle 101, the higher risk level for the second lane L2. In addition, when the first vehicle 101 is travelling at a constant speed, the processor 850 may determine such that the faster speed of the vehicle 100, the higher risk level for the second lane L2.

The processor 850 may perform a calculation of subtracting a speed of the second vehicle 102 from the speed of the vehicle 100. The processor 850 may determine that a risk level for the third lane L3 in which the second vehicle 102 is located is proportional to a value obtained by subtracting the speed of the second vehicle 102 from the speed of the vehicle 100. Accordingly, when the vehicle 100 is travelling at a constant speed, the processor 850 may determine such that the slower speed of the second vehicle 102, the higher risk level for the third lane L3. In addition, when the second vehicle 102 is travelling at a constant speed, the processor 850 may determine such that the faster speed of the vehicle 100, the higher risk level for the third lane L3.

Unlike the example of FIG. 14, when it is determined, based on surrounding situation information or data of interest, that there is a lane in which no vehicle is located, the processor 850 may determine that the lane has the lowest risk level. The lane in which no vehicle is located is safer than a lane in which other vehicle is located, and thus, the lane in which no vehicle is located may have a lower risk level.

According to another embodiment of the present invention, the processor 850 may determine a risk level for a lane of interest, by taking into consideration respective set paths for the vehicle 100 and a vehicle of interest.

Vehicle state information may include information about a set path and a control state of the vehicle 100 (hereinafter, referred to as “first information”).

The information about a control state may indicate a control state of any of various devices provided in the vehicle 100. For example, information about a control state of the vehicle 100 may indicate at least one of a speed, a braked-state, a braking force, and a steering angle of the vehicle 100.

Data of interest may include information about a set path and a control sate of a vehicle of interest (hereinafter, referred to as “second information”).

The processor 850 may determine a risk level for each lane of a multilane road, based on a determined lane-level location determined for the vehicle of interest, a determined lane-level location of the vehicle 100, the first information, and the second information.

The processor 850 may determine a predicted path to be travelled by the vehicle 100 for a specific period of time, based on a determined lane-level location of the vehicle 100 and the first information. For example, the processor 850 may determine a predicted path to be travelled by the vehicle 100 for about two or three seconds, based on the current location of the vehicle 100 and first information which is about a set path and a control state of the vehicle 100.

The processor 850 may determine a predicted path to be travelled by a vehicle of interest, based on a determined lane-level location of the vehicle of interest and the second information provided by the vehicle of interest. For example, the processor 850 may determine a predicted path to be travelled by the vehicle of interest for about two or three seconds, based on the current location of the vehicle of interest and the second information which is about a set path and a control state of the vehicle of interest.

When it is determined that a predicted path for the vehicle 100 and a predicted path for the vehicle of interest overlap each other within a specific period of time, the processor 850 may determine that a lane including a location at which the predicted path for the vehicle 100 and the predicted path for the vehicle of interest overlap has the highest risk level.

The processor 850 may determine a location of predicted collision between the vehicle 100 and the vehicle of interest, based on the predicted path for the vehicle 100 and the predicted path for the vehicle of interest. The processor 850 may determine that a lane including the location of predicted collision between the vehicle 100 and the vehicle of interest has the highest risk level.

For example, when it is determined that the vehicle 100 is going to make a lane change and that a vehicle behind the vehicle 100 in the same lane is going to make a lane change in the same direction, the processor 850 may determine that a lane to which the vehicle 100 is going to move has the highest risk level.

For example, when it is determined that the vehicle 100 is going to move to a particular lane and that a vehicle of interest travelling in a next-next lane is also going to move to the particular lane, the processor 850 may determine that the particular lane has the highest risk level.

In the example of FIG. 14, when it is determined, based on, based on information about a set path and a control state of the second vehicle 102, that the second vehicle 102 is going to move to the second lane L2, the processor 850 may determine that the second lane L2 has the highest risk level.

In the example of FIG. 14, when the vehicle 100 is determined, based on vehicle state information, to move to the third lane L3 and the third vehicle 103 is determined, based on V2V data provided by the third vehicle 103, to move to the third lane L3, the processor 850 may determine that the third lane L3 has the highest risk level.

In the example of FIG. 14, when the vehicle 100 is determined, based on vehicle state information, to move to the first lane L1 and a speed of the fourth vehicle 104 is determined to increase gradually, the processor 850 may determine that the first lane L1 has the highest risk level.

According to another embodiment of the present invention, the processor 850 may determine a risk level for a lane of interest, using driving record of a vehicle of interest.

Data of interest may include information about the driving record of the vehicle of interest.

Information about the driving record may include a previous path travelled by the vehicle of interest, and information about a speed at which the vehicle of interest previously travelled in each area.

Based on the information about the driving record of the vehicle of interest, the processor 850 may determine a risk level for the vehicle of interest.

For example, based on driving record of a vehicle of interest, the processor 850 may determine a speed of the vehicle of interest in a specific area, the number of times that the vehicle of interest makes a lane change in the specific area, and the number of times that the vehicle of interest overtakes other vehicle in the specific area. The processor 850 may determine that a risk level for the vehicle of interest is proportional to at least one of the speed of the vehicle of interest in the specific area, the number of times that the vehicle of interest makes a lane change in the specific area, and the number of times that the vehicle of interest overtakes other vehicle in the specific area. Accordingly, the processor 850 may determine that the vehicle of interest has a high risk level when at least one of the speed of the vehicle of interest in the specific area, the number of times that the vehicle of interest makes a lane change in the specific area, and the number of times that the vehicle of interest overtakes other vehicle in the specific area is same or greater than a preset value.

The processor 850 may determine that a risk level for a lane in which the vehicle of interest is located is proportional to a risk level for the vehicle of interest.

For example, when the vehicle of interest has the highest risk level, the processor 850 may determine that a lane in which the vehicle of interest is located has the highest risk level. In this case, the processor 850 may determine that lanes on both sides of the lane in which the vehicle of interest is located have a normal risk level.

In the example of FIG. 14, when it is determined that the second vehicle 102 has the highest risk level, the processor 850 may determine that the third lane L2 has the highest risk level of 2, that the second lane L2 and the fourth lane L4 have a risk level of 1, and that the first lane L1 has a risk level of 0.

According to another embodiment of the present invention, the processor 850 may determine a recommended speed for each lane, by taking into consideration a speed of the vehicle 100.

Data of interest may include information about a speed of the vehicle of interest. Accordingly, the processor 850 may determine a speed of the vehicle of interest based on data of interest.

The processor 850 may determine that a speed of the vehicle of interest determined based on speed information of the vehicle of interest is a recommended speed for a lane in which the vehicle of interest is located.

In the example of FIG. 14, the first vehicle 101, the second vehicle 102, the third vehicle 103, and the fourth vehicle 104 are located on a road corresponding to a set path for the vehicle 100, and therefore, they are all vehicles of interest. Accordingly, V2V data respectively provided by the first vehicle 101, the second vehicle 102, the third vehicle 103, and the fourth vehicle 104 are data of interest.

The processor 850 may determine a speed of each of the first vehicle 101, the second vehicle 102, the third vehicle 103, and the fourth vehicle 104, based on data of interest provided by each of them.

The processor 850 may determine that a speed of the first vehicle 101 is a recommended speed for the second lane L2. The processor 850 may determine that a speed of the second vehicle 102 is a recommended speed for the third lane L3. The processor 850 may determine that a speed of the third vehicle 103 is a recommended speed for the fourth lane L4. The processor 850 may determine that a speed of the fourth lane 104 is a recommended speed for the first lane L1.

When a recommended speed for a lane included in a set path is determined, the processor 850 may display the recommended speed on the display unit 251.

When the vehicle 100 is in an autonomous mode, the processor 850 may provide a control signal so that the vehicle 100 travels at the recommend speed for the current lane of travel.

When it is determined, based on data of interest, that there is a lane in which no other vehicle is located among multiple lanes included in the set path, the processor 850 may determine a legal top speed limit corresponding to the set path to be a recommended speed for the lane in which no other vehicle is located.

The legal top speed limit corresponding to the set path is a legal top speed limit for a road corresponding to the set path. Based on navigation information or traffic information, the processor 850 may determine a legal top speed limit corresponding to the set path.

FIG. 15 is a diagram illustrating a driving assistance apparatus according to an embodiment of the present invention determines distribution of risk levels over multiple lanes.

The processor 850 may determine respective recommended speeds or risk levels for multiple lanes L1, L2, L3, and L4 included in a set path. In addition, with reference to the vehicles 100, 101, 102, 103, and 104 located in the multiple lanes L1, L2, L3, and L4, the processor 850 may divide the multiple lanes L1, L2, L3, and L4 into multiple regions L1Z1, L2Z1, L2Z2, L2Z3, L3Z1, L3Z2, L4Z1, and L4Z2. The processor 850 may determine a recommended speed or risk level for each of the multiple regions L1Z1, L2Z1, L2Z2, L2Z3, L3Z1, L3Z2, L4Z1, and L4Z2.

When the fourth vehicle 104 is determined to be located in the first lane L1, the processor 850 may divide the first lane L1 into multiple regions with reference to the fourth vehicle 104. Although only the front region L1Z1 of the fourth vehicle 104 is shown in the example of FIG. 15, a rear region of the fourth vehicle 104 may exist. The processor 850 may determine a risk level for the region L1Z1 based on V2V data respectively provided by the fourth vehicle 104 and the first vehicle 101. The processor 850 may determine a recommended speed for the region L1Z1 based on V2V data provided by the fourth vehicle 104.

When the vehicle 100 and the first vehicle 101 are determined to be located in the second lane L2, the processor 850 may divide the second lane L2 into a region L2Z1 behind the vehicle 100, a region L2Z2 between the vehicle 100 and the first vehicle 101, and a region L2Z3 in front of the first vehicle. The processor 850 may determine a risk level for the region L2Z1 based on V2V data provided by the fourth vehicle 104. The processor 850 may determine a risk level for the region L2Z2 based on V2V data respectively provided by the second vehicle 102 and the first vehicle 101. The processor 850 may determine a risk level for the region L2Z3 or a recommended speed for the second lane L2 based on V2V data provided by the first vehicle 101.

When the second vehicle 102 is determined to be located in the third lane L3, the processor 850 may divide the third lane L3 into a region L3Z1 behind the second vehicle 102 and a region L3Z2 in front of the second vehicle 102. The processor 850 may determine a risk level for the region L3Z1 based on V2V data respectively provided by the third vehicle 103 and the second vehicle 102. The processor 850 may determine a risk level for the region L3Z2 based on V2V data respectively provided by the second vehicle 102 and the first vehicle 101. The processor 850 may determine a recommended speed for the third lane L3, based on V2V data provided by the second vehicle 102.

When the third vehicle 103 is determined to be located in the fourth lane L4, the processor 850 may divide the fourth lane L4 into a region L4Z1 behind the third vehicle 103 and a region L4Z2 in front of the third vehicle 103. The processor 850 may determine a risk level for the region L4Z1, based on V2V data provided by the third vehicle 103. The processor 850 may determine a risk level for the region L4Z2, based on V2V data respectively provided by the third vehicle 103 and the second vehicle 102. The processor 850 may determine a recommended speed for the fourth lane L4, based on V2V data provided by the third vehicle 103.

FIGS. 16 and 17 are diagrams illustrating a driving assistance apparatus according to an embodiment of the present invention sets a recommended path necessary for a lane change.

Based on information about a set path for the vehicle 100 and vehicle state information, the processor 850 may determine whether the vehicle 100 needs to change a lane.

For example, the processor 850 may determine the current lane of travel in which the vehicle 100 is located, based on GPS location information and surrounding image information of the vehicle 100 included in vehicle state information. Then, when it is determined, based on information about a set path and a location of the current lane of travel, that the vehicle 100 needs to make a lane change in order to travel along the set path, the processor 850 may determine that the vehicle 100 needs to change a lane.

For example, based on the vehicle state information, the processor 850 may determine whether a turn signal light of the vehicle 100 is turned on. When the turn signal light of the vehicle 100 is turned on, the processor 850 may determine, based on surrounding situation information, whether there is a lane for the vehicle 100 to move in a direction corresponding to a direction indicated by the turn signal light. When there is a lane for the vehicle 100 to move in the direction corresponding to the direction indicated by the turn signal light, the processor 850 may determine to make a lane change in the direction indicated by the turn signal light.

When it is determined that the vehicle 100 needs to make a lane change, the processor 850 may determine, based on data of interest and vehicle state information, a timing for lane change (hereinafter, referred to as a “lane change timing”).

For example, the processor 850 may predict a path and a location of a vehicle of interest based on data of interest. Based on the predicted path and location of the vehicle of interest, the processor 850 may determine a lane change timing at which a lane change would not lead to a collision between the vehicle and the vehicle of interest.

The processor 850 may set a path, along which the vehicle 100 is able to make a lane change at the determined timing, as a recommended path.

In the examples of FIGS. 16 and 17, the driving assistance apparatus 800 may determine a lane change timing depending on a driving mode of the vehicle 100.

Referring to FIGS. 16A, 16B, 16C, when the vehicle 100 is determined to be in a speed mode based on vehicle state information, the processor 850 may determine a relatively early lane change timing.

If it is determined, based on a distance between the vehicle 100 and the second vehicle 102, the vehicle 100 is allowed to make a lane change in front of a second vehicle 102 while the second vehicle 102 is travelling at 100 km/h in a lane to which the vehicle 100 is going to move, the processor 850 may adjust a speed of the vehicle 100 to 100 km/h.

The processor 850 may set a path, along which the vehicle 100 accelerates to 100 km/h and then make a lane change in front of the second vehicle 102, as a recommended path.

When the vehicle 100 is in the manual mode, the processor 850 may display, on the display unit 251, a message which indicates acceleration of up to 100 km and a recommended path for making a lane change in front of the second vehicle 102.

When the vehicle 100 is in the autonomous mode, the processor 850 may control the vehicle 100 to travel along the recommended path. The processor 850 may perform a control action such that the vehicle 100 accelerates up to 100 km/h and then makes a lane change in front of the second vehicle 102.

Referring to FIGS. 17A, 17B, 17C, when the vehicle 100 is determined in a safe mode based on vehicle state information, the processor 850 may determine a relatively late lane change timing.

Even in the case where it is determined, based on a distance between the vehicle 100 and a second vehicle 102, the vehicle is able to make a lane change in front of the second vehicle 102 while the second vehicle 102 is travelling at 100 km/h in a lane to which the vehicle 100 is going to move, the processor 850 may determine a lane change timing at which the vehicle 100 would make a lane change after the second vehicle 102 passes.

The processor 850 may set a path, along which the vehicle 100 would make a lane change after the second vehicle 102 passes, as a recommended path.

When the vehicle 100 is in the manual mode, the processor 850 may display, on the display unit 251, a recommended path for making a lane change after the second vehicle 102 passes.

When the vehicle 100 is in the autonomous mode, the processor 850 may control the vehicle 100 to travel along the recommended path. The processor 850 may control the vehicle 100 to make a lane change after the second vehicle 102 passes.

Based on data of interest, the processor 850 may further determine a recommended speed for a lane to which the vehicle 100 is going to move.

The processor 850 may display, on the display unit 251, the recommended speed for the lane to which the vehicle 100 is going to move.
